Resistência à Flexão de Vigas de Concreto Armado Reforçadas com Fibra de Carbono

Abstract

This work investigates the flexural resistance of reinforced concrete beams strengthened with carbon fiber reinforced polymer (CFRP). The study presents a theoretical and experimental analysis of strengthened beams, highlighting the factors that influence the behavior and resistance of these structures. Thirty-seven tests of beams strengthened with CFRP were analyzed, and the results indicate that the flexural reinforcement ratio before and after strengthening is a determining factor for the performance of the beams. The study proposes a complete methodology for analyzing the behavior of the beams, aiming to maximize the efficiency of the strengthening.
